Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for cultivating flowering trees such as tea plants and Satsuki azaleas, and more specifically, to prevent freeze damage and frost damage to these flowering trees, as well as to The present invention relates to a cultivation method that promotes germination and growth.

"Prior Art" and "Problem to be Solved by the Invention" Tea plants in tea plantations in cold regions are planted at a height of about 6 meters above the ground where warmer air exists than at the ground surface to prevent new buds from being damaged by frost. A frost damage prevention method in which an anti-frost fan is installed and warm air is blown onto the tea trees to prevent the formation of frost has become widespread, and is said to be reasonably effective.

However, this anti-frost fan is the only way to prevent frost damage.
In order to use naturally occurring warm air around 3000 ft, the rate of early spring, topography, and region, from February to March, when warm air is difficult to generate, is
It is not effective on cold days, etc., and its use period is limited to the warm spring season, and even if this anti-frost fan is installed,
New shoots may be damaged by frost or cold damage.

Since this anti-frost fan is an erected structure in a tea plantation, it becomes an obstacle during automatic tea picking, impairing work efficiency and causing problems in the aesthetic appearance of the field.

The present invention solves the above-mentioned problems of the conventional art.

The present invention provides a cultivation method for promoting the germination and growth of flowering trees in cold seasons and cold regions.

``Means for Solving the Problems'' The cultivation method of the present invention that solves the above technical problems is to ``build hot water pipes in the ground near the roots of flowering trees such as tea plants, at a short distance from the ground surface to provide hot water. A first invention of ``a cultivation method characterized by cultivating by circulating and supplying water to raise the soil temperature''; The cultivation method comprises heating the soil and gradually releasing water or liquid fertilizer mixed water from the watering pipe.

``Function'' The cultivation method of the present invention described above increases the soil temperature near the roots of flowering trees through underground water supply pipes, and as the soil temperature rises, the surface temperature rises and warms the surface air. The air rises and wraps around flowering plants such as tea plants, preventing dew and freezing damage.

This means of raising the ground temperature using hot water pipes is not limited by the period of use or the topography, and moreover, it is possible to artificially control the ground temperature by controlling the temperature of hot water, so around February when conventional frost protection fans cannot be used. (in the central region of Honshu), and can be effectively utilized as a sufficient and effective means of preventing frost and freezing damage. This rise in soil temperature is accompanied by a germination-promoting effect that activates the roots of flowering plants, leading to earlier germination and improved germination rates.

On the other hand, in the second aspect of the present invention, water is gradually released into the ground from the sprinkler pipe installed above the hot water supply pipe, and the humidity in the ground is improved, so that the heat conduction is caused by the water in the ground.

The above-mentioned effect of raising the temperature of the ground by the hot water pipes is further promoted and the ground temperature is made uniform, and the heat capacity of the ground increases.Furthermore, the water in the ground actively evaporates into the cold surface air, so for example, tea plants are grown. When covered with an m-mesh mesh, the warm vaporized water fills and wraps inside the cover, which has a unique effect of making the freezing damage prevention effect even more pronounced.

"Example" Hereinafter, a detailed explanation will be given based on an example. First, an embodiment of the present invention applied to a tea plantation will be explained based on FIG.

In this example, in order to confirm the effects of the cultivation method of the present invention, the required space of a tea plantation in Shika City, Mie Prefecture was set up as an experimental area, and the tea fields adjacent to the experimental area were covered with conventional anti-frost fans. It was cultivated in the target area for comparison purposes. That is, a looped hot water pipe 2 with an inner diameter of 25 millimeters is buried in the ground to a depth L2 = 30 cm in the middle of a furrow 1 with a spacing of 1.5 meters between tea tree furrows, and a hot water tank 4 is installed. By recirculating hot water at 25 to 30 degrees Celsius from the ground, the soil temperature was heated to prevent tea tree vinegar from frost and cold damage, and to promote germination. In addition, 4 in the figure is a hot water tank, 5 is a hot water supply pump, and 8 is an automatic temperature control valve.

The above soil temperature heating treatment is applied from February to April, when the tea plants begin to germinate and are at risk of frost damage and cold damage.
When the application was applied over a period of ~May, the underground temperature was always maintained 4 to 5 degrees higher than the target area (compared to the same measurement location), and the above effect was achieved, no frost damage occurred, and the germination period was maintained. This is extremely favorable, as the growth rate is considerably earlier than in the target area, the density of sprouting is good, the first tea can be picked 7 days earlier than in the target area, and the actual yield of tea confectionery per unit of tea increases by about 10%. The cultivation effect was confirmed.

Next, an embodiment of the second invention will be described based on FIG. In this embodiment shown in FIG. 2, in the experimental area of the embodiment shown in FIG. 7 (a well-known nozzle that consists of a spongy spout and gradually sprinkles water using the water pressure inside the pipe) was installed, and at the same time as the hot water supply pipe 2 was feeding water, water was supplied to the water sprinkling pipe 6 to sprinkle water underground.

According to this embodiment, underground moisture increases due to water dissipated from the water supply pipe 6, so that the underground thermal conductivity of the hot water supply pipe 2 improves, the underground heat capacity increases, and furthermore, the heated underground moisture increases. As it rises near the ground surface, the surface temperature becomes even higher, and during the radiation cooling at night, warm vaporized water actively occurs in the cold surface air, which has an extremely effective effect of protecting tea tree vinegar.

In other words, the actual measurement result of the rise in soil temperature when using this sprinkler pipe 6 is as shown in Figure 2 (B), and the soil temperature comparison between the experimental area and the target area is approximately 4 to 5 degrees Celsius at a depth of 3oα, and 15a
It is clear that the experimental area has a ground surface temperature that is considerably higher than the outside temperature, which supports the above-mentioned phenomenon of vaporized water generation.

According to the embodiment shown in FIG. 2 described above, the effect of the embodiment shown in FIG.
The cover is filled with vaporized water generated from the ground, making frost and cold damage prevention even more effective.

The cultivation method of the present invention is extremely effective for Satsuki azalea, which is susceptible to cold damage and frost damage, and is widely used to prevent freezing damage and promote germination of other flowering plants and general plants that are susceptible to freezing damage. It is something to be applied.

"Effects of the Invention" As explained above, the method for cultivating flowering trees such as tea plants of the present invention is based on a soil temperature heating means, so it is effective in preventing frost and freezing damage regardless of the time of year or topography. , has a cultivation effect that promotes active germination and growth due to rising soil temperature, and is achieved by underground facilities rather than erected structures in the field, which may interfere with tea picking work or impair the aesthetic appearance of tea fields. It has many effects such as not causing any harm.
